“…Orthogonal utilization of X‐bonding and H‐bonding has been recently exploited in coordination chemistry for constructing various metal complexes with different supramolecular assemblies. In this regards, a new molecule was designed, 4‐iodo‐ N ‐(4‐pyridyl)benzamide ( IPBZA ), which has the versatility to engage in different interactions owing to its multiple functionality (Figure 21B) [106] . Single crystal structure of IPBZA revealed 2D sheet formation by N⋅⋅⋅I halogen bonding and perpendicular N−H⋅⋅⋅O=C carboxamide hydrogen bonding.…”

Polymers have long been known to us for their versatile utility in our daily lives. With many years of successful advancement in controlled polymer synthesis and supramolecular chemistry, currently an amalgamation of these two fields is becoming increasingly important for generating modern‐day emerging polymeric materials. Hydrogen bonding and other noncovalent interactions like π‐stacking, host‐guest interaction, electrostatic interaction, metal‐ligand coordination have been explored much to this context, unlike the recently emerged halogen bonding, which indeed shows advantageous features like superior hydrophobicity, directionality and polar solvent resistance compared to ubiquitous hydrogen bonding. Hence, rendering these properties of halogen bonding into polymeric domain for generating functional materials for application in advance nanotechnologies is highly desirable. In the recent years, substantial progress has been made in fulfilling this challenging goal. This is evident from the escalating number of scientific publications in this research area every year. In this minireview, we have summarized the most recent developments in the field of halogen bonded polymeric assemblies and supramolecular polymers and discussed them in the context of their emerging materials properties and functions. Emphasis is given on highlighting various design criteria adopted in crystal engineering, covalent and supramolecular polymers in the past five years for constructing diverse organic functional materials, viz. liquid crystals, photoresponsive and photochromic materials, biomaterials and gels, self‐healing materials and many others by virtue of this highly directional supramolecular tool. In conclusion, a brief perspective on the advantages, challenges and future prospects in this rapidly growing field of research is discussed.

In this study, the molecular and crystal structures of iodocymantrenes [Mn(C5InH5−n)(CO)2(PPh3)] (1b n = 1; 2, n = 2; 3, n = 3) are reported and compared with the known structures of [Mn(C5InH5−n)(CO)3] (1a, n = 1; 5, n = 5) and [Mn(C5I4H)(CO)2(PPh3)] (4). In the crystals, many weak interactions like H bonds (H…O, H…I, H…π), halogen bonds (I…I, I…O, I…C, I…π), and π-π contacts are found. Hirshfeld analyses show that H bonding is far more important when the PPh3 ligand is present, and this is mainly based on dispersive interactions. However, without the PPh3 ligand, H…I and other I…X contacts are the most frequently observed intermolecular interactions.
